1 Claim. "i

This invention relates to earth working implements.

An object of this invention is to provide a device in the form of adigger or scraper, which is designed to scrape and collect the dirt orother material, and which can be adjusted so as to pick up either apartial or full load.

Another object of this invention is to provide a device of this kindwhich includes improved latching means for latching the scoop in eitherscraping position or in dragging position.

A further object of this invention is to provide a device of this kindhaving a renewable scraping blade and runners on the bottom so as toprotect the bottom against undue wear.

A still further object of this invention is to provide a rotatable'scraper which when towed behind a tractor or other suitable towingmeans may be selectively used as a digger. scraper, or spreader and as acarrier of a load and when pushed may be used as a bulldozer.

Yet a further object of this invention is to provide a rotary scraper ofthis kind having selective control means for fixing the scraper inrotated position and independant control means for selectively adjustingthe angle of the cutting blade with respect to the earth.

Still another object of this invention is to provide -means for anoperator to selectively control the position of the rotatable scraperand the position of the cutting blade with respect to the earth duringoperation of the scraper.

With the above and other objects in view, my invention consists in thearrangement, combination and details of construction disclosed in thedrawings and specification, and then more particularly pointed out inthe appended claim.

Referring to the drawing, the numeral l5 designates generally a drawbarassembly Which is adapted for attaching a rotatable scoop I6 behind atractor or other suitable machine for towing and/ or pushing the scoopI6. The drawbar assembly I5 has secured to its forward end an attachmentplate Il by which the drawbar I5 is attached to the tractor by means ofa shackle I8.

The plate Il is formed at its front end with a plurality of verticallyspaced apart openings I9 to any one of Iwhich the shackle I8 may beattached for initially adjusting the drawbar to a desired angularposition relative to the tractor and the earth. The drawbar I5 is formedwith a pair of rearwardly divergent arms 2li and a connecting bar ZIbetween the ends of the arms 2S. Extending rearwardly from the divergentends of each arm 28 and the bar 2| there is yattached a drawbarconnecting plate 22. v The plates 22 are each formed with a segmentalarcuate opening 24 near the rear end into which the scoop I6 is adaptedto be engaged.

The scoop I6 is formed of an open sided or partial cylinder having abottom surface 25. A cutting blade 26 is secured below the surface 25 bybolts 21 or other suitable fastening meansand skid plates 2S are fixedto the bottom 25 behind the blade 26 to prevent injury to the bottom ofthe scoop IE, Also fixed to the ends of the scoop I6 are skids 29 aboutpart of the open side of the cylinder to prevent damage to the edges ofthe ends of the cylinder. Trunnions 3i! fixed to the end walls of thescoop I 6 extend outwardly therefrom and are adapted to engage in thearcuate slot 24 of the drawbar connecting plate 22.

Fixed to each end wall of the scoop IB are stop bars 3l, 32 and 34 whichextend therefrom and are formed with a straight edge on one side and abeveled edge on the opposite side. The stop bars 3i and 32 are used tohold the scoop I6 in position for digging and spreading respectively,while the bar 34 is used to hold the scoop I6 in position for unloading,bulldozing or travelling empty. Since the stops 3l and 32 are used indragging the scoop I5 and stop 34 is sometimes used in pushing the scoopI6, the beveled edge of stop 3d is reversed from that of stops 3| and 32in order that the straight edge of stop bar 34 will properly engage thelower face of plate 44 for bulldozing.

For holding the scoop I6 in selected rotated position there is provideda locking or trip lever assembly which is carried by the drawbar andengages the scoop |16 through stops 3l 32, and 34. This locking assemblyconsists of a pair of trip lever supporting plates 35, one on each sideof the cylinder I6. The support plates I35 are tending arm 49.

formed of a triangular plate having a pair of obtusely related edges.The plate 35 is pivotally mounted-on the drawbar connecting plate 22 bya pivot pin 36 at the obtuse angle, the plate 35 providing a leverhaving a rearwardly extending arm 31 Aand a vertical arm 38. The rearend of the arm 31, between the drawbar plate 22 and scoop I6, is formedwith a bearing in which the trunnion 30 is rotatably engaged.

A trip lever rod 39 is loosely engaged in the upper end of the arms 38and extends across the front of the scoop I6. Fixed to the trip leverrod 39 and extending upwardly therefrom is a trip lever 40, which issupported on the rod 39 by struts 4|. Also fixed to the rod 39 bywelding or other suitable means, at each end is a lock lever 42 whichextends rearwardly from the rod 39, and having a short forward extension43.

A lock plate 44 is xed to the rear end of the lever 42 and extendsapproximately perpendicular thereto and is adapted to be engaged by thestops 3|, 32, and 34. A spring 45 between the plate 44 and the rear endof the lever 31 constantly pulls the lock plate 44 rearwardly intolocked position. A stop 46 fixed to each plate 35 engages the upper sideof the lever arm 43 to limit the rearward movement of the lever 42.

A second control lever 41 is pivotally carried by the cross car 2| ofthe drawbar I 5 by a pair of ears 46, xed on the bar 2|. The lever 41 isformed of an L-shaped member having a rearwardly ex- A link 50 connectsthe rear end of the arm 49 to the trip lever rod 39. The rear end of thelink 50 is fixed to a sleeve or bearing 5I rotatable on the rod 39. Astop member 51 is fixed on the upper end of each of the ears 48 and isengageable with the lever arm 49 to limit theupper swinging of the arm49 and the toggle action of the link 5U. The control lever 41, orpartial load lever, is used to control the angle of the cutting blade 26by raising or lowering the front end of the scoop |6 when the scoop I6is locked against rotation.

' In the use and operation of this assembly, when the trip lever 40 ispulled forward, as by a rope 52 in the hands of an operator, as thetractor proves, the scoop I6 is free to rotate. To use as a digger, thelever 40 is pulled forward and the scoop I6 allowed to rotate until thestop 3| approaches the lock plate 44, at which time the lever 49 ispermitted to be pulled rearwardly by springs 45, and the lock plate 44engages the forward edge of the stop 3| preventing further rotation. Asthe scoop I6 becomes lled with material, the weight of the material,acting through `the linkage arrangement of plates 35 and 22, ro-

tates the scoop I6 against the dragging force and moves the blade 26 tonon-digging or slightly raised position.

V For spreading material from the scoop I6, the tllled scoop I6 ispermitted to rotate until the stop 32 is engaged with the lock plate 44at which time the blade 26 is partly behind the scoop I6 and the openside is dragging on the ground, thus permitting material to be spread onthe ground.

For unloading the scoop I6, the scoop I6 is permitted to rotate untilthe beveled side of stop 34 is engageable with the rear side of plate44, at which time the open side of the scoop I6 is rearward, permittingthe material to freely fall from the scoop I6.

Pushing or bulldozing may be accomplished by allowing the scoop I6 torotate until the stop 34 has passed the lock plate 44, then the lockplate 44 is dropped into place so that the straight edge of the stop 34engages the lower or forward side of the lock plate 44 and the scoop maythen be pushed rearwardly.

When it is desired to carry a partially filled scoop I6, with the scoopin digging position, thc partial load lever 41 is pulled forwardly by arope 52a by the operator, thus raising the rod 39 by means of link 50and pivoting the plate 35 abouts its pivot 36, rotating the scoop I6 sothe blade 26 is raised above the earth. To lock the scoop I6 in thisposition, it is necessary only to pull the lever 41 forwardly until thepivot 53 between the arm 49 and link 50 is above a straight line betweenthe rod 39 and fulcrum 54 of lever 41. To release the scoop |6 from thisload carrying position, the lever 41 is let free and the lever 4U movedforwardly until the L-shaped bar 55, ixedon the lever 4D engages thelink 50 to move the pivot 53 below the line between bar 39 and thefulcrum 54.

I do not mean to conne myself to the exact details of constructionherein disclosed, but claim all variations falling within the purview ofthe appended claim.

What I claim is- In combination a rotatable scoop, a drawbar for saidscoop and means for selectively positioning said scoop relative to saiddrawbar, said drawbar including a pair of rearwardly extendingconnecting plates, each of said plates formed with a segmental arcuateopening, a trip lever supporting plate pivotally secured to saidconnecting plates, trunnions on said scoop rotatable in said supportingplates and engageable in said arcuate openings, a trip lever rodpivotally secured between said supporting plates, a trip lever xed tosaid rod, spring pressed locking members xed to said rod, and stop orlocking bars on said scoop engageable with said locking members, asecond lever pivotally mounted on said dravvbar, and a link looselyconnected to said rod and said second lever for pivoting said supportingplate relative to said drawbar.
